I think this upgrade will be the first one to be free. What do you think? In the past they have always given a price when they announced an OS upgrade, right?. No price this time. I feel like it is better to not give a price and surprise us with it being free than it is to not give a price and then surprise us with one later. If there were a price, then they should have announced it. Also this release is low on big upgrades. It just adds polish. I can see people shelling out $20 for Notification Center, iCloud, iMessages for Mac, etc. but not so much for Maps and iBooks apps.
